The lower half of the end of the arnanca, in the county of Oattaraugus and board is extended, as .at 14, beyond the 5 State of New York, have invented a new and upper edge 1l, and the Lipper' face thereof is 55 useful Roof-Board Joint, of which the followinclined upwardly and provid ed with an outing is a specication. v wardly and upwardly projecting tongue This invention relates to certain improveformed thereon. This extension inclines recrnents in the construction of roof-boards for tilinearly in a downward direction from the 1o buildings whereby a suitable tight joint is lower end of the tongue 15 and forms the 6o maintained and leaking at the joint pre* lower vertical face 16. The upwardly-invented. clined surface of the extension 14 is provided The object of the invention is to provide a at the base of the tongue 15 with a waterjoint formed by interlocking two double channel 17, thns'necessitating any water that 15 tongue-and-grooved members, which promight get into the joint to pass the channel 65 duces a joint that is impervious not only to 13 and then up the incline before reaching water, but also to cold. the channel 17.

I claim as my inventionl. A rooting-board having its edges provided each with two vertical faces arranged one in advance of the other and with an intermediate tongue and a groove disposed obliquelyto the faces.

2. A rooting-board having its edges provided each with two vertical faces arranged one in advance of the other and with an intermediate tongue and a groove obliquely disposed at right angles to the said faces.

4. A rooiing or sheathing composed of boards laid edge to edge, one edge of one hoard being provided with two vertical faces and an intermediate tongue and a groove, the tongue being downwardly inclined and the opposing edge of the other board being provided with two vertical faces and an intermediate tongue and groove, the tongue being upwardly inclined, the latter tongue having its upper face provided with an intermediate groove constituting a water-channel, and the groove proper being of greater depth than the length of the tongue of the othell board to present a water-channel.

5. A roong or sheathing composed of boards laid edge to edge, the exposed faces of the boards being corrugated, and the opposed edges of the boards being provided with vertical faces disposed one in advance of the other and with angularly-disposed tongues and grooves adapted to interlock, one of the tongues being provided with an intermediate water-channel and the groove adjacent thereto having it-s terminal constituting a waterchannel, and a hatten secured over the meeting edges of the boards.
